为研究型钢混凝土边框-开洞钢板-混凝土组合剪力墙的抗震性能,进行了5个不同设计参数、不同构造措施剪力墙试件抗震性能比较试验研究.各试件的剪跨比均为1.5,采用低周反复荷载加载.基于试验,对比分析了各试件的承载力、刚度、延性、滞回耗能和破坏特征等.研究表明：与普通钢筋混凝土剪力墙相比,型钢混凝土边框内藏钢板组合剪力墙承载力高、延性好、刚度退化慢、耗能能力强；适当的内藏钢板厚度可改善型钢混凝土边框内藏钢板剪力墙的抗震性能；内藏钢板厚度相同时,设拉结钢筋试件的抗震性能优于焊接栓钉的试件.基于试验提出了型钢混凝土边框内藏钢板剪力墙的承载力计算模型,计算结果与实测值接近.

Five shear wall test models with different design parameters and different construction measures were compared to study the seismic performance of composite shear walls with shaped steel concrete boundary columns and embedded steel plates. The shear span ratio of all the models was 1. 5. The models were tested under low cyclic loading test. The bearing capacity, stiffness, ductility, hysteretic energy dissipation and failure characteristics of the models were comparatively analyzed. The results show that compared to the shear walls with shaped steel concrete boundary columns,the composite shear walls with shaped steel concrete boundary columns and embedded steel plates show better seismic performance, in that the load-bearing capacity, the ductility and the seismic energy dissipation capacity are improved greatly; the composite shear walls with proper thick embedded steel plate show better seismic performance;the composite shear wall modes which embedded steel plate and reinforced concrete are connected by steel bars show better seismic performance compared to the composite shear wall models which embedded steel plate and reinforced concrete are connected by stud welded to the steel plate. The bearing capacity calculation models of the composite shear walls with shaped steel concrete boundary columns and embedded steel plates were proposed in this paper and the load-bearing capacity of the shear walls calculated by the models aere in good agreement with the experimental results.
